1710J-Series Waveform Monitors
10. Use the VERTICAL position control to place the signal blanking level on the
baseline.
11. Select X5 GAIN.
12. Check for less than 1 major division of baseline shift when switching
between X1 (Gain off) and X5 GAIN.
13. Turn off X5 GAIN.
14. Remove the connections from the 1710J-Series Waveform Monitor CH B
input.
15. Change the 75
W
coaxial cable with the VAC signal to the CH B input. Do
not terminate the loop-through.
16. Set the VAC for a 999.9 mV square wave.
17. Check that the vertical amplitude of the display is 138.6 to 141.4 IRE
(0.990 V to 1.010 V).
18. Disconnect the VAC from the 1710J-Series Waveform Monitor.
The requirement is 1 V
±
1%
1. Push the REF button and hold it in until the calibrator signal is displayed.
2. Check the 1710J-Series Waveform Monitor for a displayed amplitude of
138.6 to 141.4 IRE PAL (0.990 V to 1.010 V).
The requirements are
H
Attenuation of 60 Hz input signal 20% or less
H
Blanking level shift with APL change, less than 1 IRE (7 mV)
H
Blanking level shift with presence or absence of burst, less than 1 IRE
(7 mV)
1. Use a 75
W
coaxial cable to connect the television test signal generator
modulated five-step linearity signal (with AC Bounce on) to the 1710J-Se-
ries Waveform Monitor CH B input. Terminate the remaining side of the
loop-through input with a 75
Ω
end-line terminator.
2. Use a 75
W
coaxial cable to connect the television test signal generator black
burst signal to the 1710J-Series Waveform Monitor EXT REF input.
Terminate the remaining side of the loop-through input with a 75
Ω
end-line
terminator.
3. Move A3J99 to the 2-3 position, Fast DC Restorer.
